44. The student packet is broken up into two lessons. pages 1-2 vocabulary
pages 3-4 combining like terms.
The PPT guides students through the lessons by giving them information and providing practice. Some slides ask the student to write something down and the answer will appear once the “answer” button is clicked. Some slides have multiple choices and the correct answer will be highlighted once clicked.
There are many ways to use this product
teaching new material
whole class review
independent practice
centers
students watch PPT and follow along with the student packet.
students complete the packet first and then self correct with the PPT.

45. Common Core State Standards covered in this lesson.
6.EE.3 Apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3(2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6(4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y.
(This activity covers combining like terms which is the part that I highlighted)
